Pulmonary lymphomatoid granulomatosis evolving to large cell lymphoma in the skin.

Lymphomatoid granulomatosis is an angiodestructive, angioinvasive lymphoproliferative disorder. It involves most frequently lungs, central nervous system and skin. Recent studies indicate that lymphomatoid granulomatosis is an Epstein-Barr virus associated B cell disorder with a background of reactive T lymphocytes. In a 49 year old woman presenting with fever, malaise and pulmonary masses the diagnosis of lymphomatoid granulomatosis was established histologically by open lung biopsy. Following the initial diagnosis the patient was found to have gastric and skin involvement. The skin lesion was diagnosed as diffuse large B-cell lymphoma.
